I have recently discovered walking rail lines and finding insulators. It becomes addictive haha. I have found an abandoned lumber railway that operated from around 1905-1950s in my area. I’ve walked a little of it and found poles in the piles of trash, however I haven’t seen any insulators or wire yet. My dumb question is did most railroads, including short lines and lumber/mining railroads, have communication lines on them? Or were they primarily only on the major lines? I’m trying to decide if it’s worth exploring more in depth.
